To all whom it may concern:

Be it known that 1, Leon R. Rios, a citizen of the United States,residing at Hereford, in the county of Deaf Smith and State "of Texas,have invented new and useful inn bar an the pins Pins 14 extend throughand openings 12 While the provements in Nut-Locks, of which the following is a specification.

My invention relates to a nut loci; particularly for association with aiisn plate and a plurality of nuts. I principally aim to provide a nutlock having a spring mou ting locking pins at each on having bluntsurfaces and inclined surfaces, with the inclinations so arranged thatthey "nay be provided by passing the article but once through a machineand may flatly engage locking grooves of the nut by mounting the bar ona fish plate diagonally.

With the above and serviont objects, such as will appear hereinafter inview the invention has been embodied in one preferred form asillustrated in accompanying dra n ings wherein:

Figure l is a side elevation or" a nut conforming to my invention; Fig.2 is a bot-tom view thereof; Fig. 3 is a vertical sectional view througha rail and fish plates showmg my improvements associated. therewith;

Fig. a is a perspective view. of a fragment of a fish plate used with myinvention; Fig. 5 is a plan View of the locking bar; anel' 6 and 7,respectively are fragmentary sicle and to views of one end of thelocking;

thereon.

Referring specifically to the drawings, show by way of example a rail in3, having fish plates 17 on the opposite s des thereof as usual. Thefastening b l ing through these conventional parts are a ignated 6 andtheir bolts numbered My improvements cooperate with g nuts, To this endI provide an openin and openings 11 and 12 through one of the fishplates and a locking bar 10 wit} bolt 15 and locking pins 14. Thiscoking normally curved as shown in l of spring metal; in use spacebetweenthe web of the rail'aol fish plate which mounts it as seen in 3.beyoi'icl the bolt 15. passes through thwopenin 13, receiving its nutbeyond the opening. he not is normally ti mteneii so asto tension bar101 The plate not materially weakened by the provision of the oyenings.

The pins lei have has or blunt sneeze as shown and. inclined walls 14".walls cooperaze wit inclined Walls Sect undercut grooves of. the nut- 8.y

In use, the nuts are held against loosening by the engagement of thegoins 142 with the grooves oi the nuts. llaidnuts, however may be freelyturned in the opposite direction until they are tight. As the nut turnsincli eclwalls 8* puslrthe pins .inwa: against 1e tension of the springbar it. in ordei; to loosen the nuts,,pins or suitable instruments maybe inserted through the opening 11 to pry the bar and oins out ofengagement with the nuts temporarily.

By reason of the blunt and fiat walls le cl 14%". avoid. pins which havesharp walls or poiits anti which do not wear Welland prove practical invery important feature of the present is the cliag'onal or an lardisposition of the bar 10. Due to the rainsl i having the walls lieaten-Cong; in the same general, direclElGllilBCl anol such as i withthe fllii, ancl endn 3 cor hination a fish resilient bar iiisgioseciour?ace of the plate. anti. itenciing therethrongh towarcl "t r sorta-3efastening colts extending one fish plate, nuts on said bolts havinggrooves in their inner suriaces, each groove having Iiiiilihi i clineclwail eXtenriing' from one oi to the other line sai i pins havinginclined walls and. said. bar beingrlisposed an 2111-.

each groove having radial side lines and an inellned wall extending fromone of the lines to the other line, and said bar being 1 disposed at anangle whereby said inclined walls thereof will spring flat against theinclined walls in the grooves.
